Ok, thanks for the answers ... 2 more questions:


1 - Is there any posibility taking the radio + CID to Vauxhall dealer and connecting TECH2?  (remember, no car pass, no VIN ...)

2 - When I connect "My Naff Code Reader" interface (080114 software), I go to NCDR1100 and click on measuring blocks, I can read "theft protection -- unit disabled". I can read the same when I click on CID display. But DISPLAY SAFE appears everytime and not blinking. What's the meaning of that?

Easy enough from an electronic perspective, suspect my visual basic is a bit to limited to do the software though!

An MPC2515 microchip demo board might do the job....

Has basic software and USB support....

Sourcing one might be a bit harder though!

vb may not be a good tool for this, unless there is a dll (and likely a sys) provided by someone. vb is a bit pants for dlls, and can't do sys files at all.

1 - Yes, but what do you hope to achieve? Tech2 cannot decode without the initial pairing code. So if its depairing, you will need the code.

2 - Not familiar with "My Naff Code Reader", but if Unit Disabled, that sounds like the unit has had 10 attempts to depair, and is now a doorstop. We have yet to find a way around this.  Of course its possibly "My Naff Code Reader" means that Security code is active, and there are still attempts left, but the real Tech2 does say attempts remaining on next line after the Security state.

That's a nice bit of kit! And if I am right you get two boards to play with in the eval kit.

The microchip eval boards are normaly VERY good (and cost effective)

The fact it can sniff means that it should be possible to identify the CN headers for display/audio and then interpret the codes being passed between them.
